 Bigger Bigger  Smaller Smaller  Reset Reset

Greetings users,

Ok, so lets review what we know;

*The LCD shield (3.2" Hiduino TFT LCD), once inserted into the UNO stays a white screen or flickers. (It stays white for me)
*A breadboard is recommended to move towards resolution and we have ruled out inserting it directly into the UNO board
(resolution being to at least get data displaying on the screen)
*Upon compiling the code given by the seller (also available by nuwud's Dropbox, props btw) it seems the code runs into a invalid line: TFTLCD tft(LCD_CS, LCD_CD, LCD_WR, LCD_RD, LCD_RESET);                 Note: I also get this. Although I got the code from the seller via email request over eBay.
*Cut LCD_RD trace and soldered it to 5V.
Cut 3.3V Trace and soldered it to 5V.
So does this mean that the 5V slot on the UNO requires two wires going into it?

Do we agree that this is the consensus?

Extras: I am awaiting a response from the same trader that focuses on asking some of these questions. I will let you know when I receive an update.

I had the same flickering white lines om mega (5V).

Put the same display om "Freaduino" (can switch between 3.3V and 5V)
Result:
  Perfectly OK when running on 3.3V
  White, flickering lines when running on 5V

Maybe as simple as a resistor in series with each dataline can to the trick of reducing input voltage
in the right direction...
